With the help of GET method one can see the parameter name(s)/value(s) appended in the URL as QueryString while submitting the form.

On the other hand the TRACE method simply returns the headers sent with the TRACE request and this is used for debugging purpose, which is not the case with the GET method

EDIT :: TRACE allows the client to see what is being received at the other end of the request chain and use that data for testing or diagnostic information. ---------------------------------------------------------------------------
